Agent Hub Facts Lookup

Choose this endpoint when you need fast, encyclopedic fact grounding for a person, place, organization, or concept — especially when you need structured data fields like founding date, coordinates, or population alongside a readable summary. Prefer it over web scraping when Wikipedia/Wikidata coverage is sufficient and you want clean, structured output without parsing HTML. Ideal for RAG pipelines, agent fact-grounding steps, or enriching entity records with canonical knowledge-graph data.

• No matching Wikipedia article found for the query — returns empty or low-confidence result
• Ambiguous query matches wrong article — summary and facts may refer to an unintended subject
• Wikidata fields partially populated — some structured facts (e.g. population or coordinates) may be absent if not in Wikidata
• Non-existent language edition requested — falls back or errors if the specified language Wikipedia lacks the article
• Rate limiting or payment failure — HTTP 402 if payment not processed correctly
